Young Heroine from Old Legacies = She has enemies from her parents (and maternal grandmother/great-grandmother) that she doesn't even really know about. She has been told stories and given information about things that she doesn't even really have the experience to understand. She still has faith in humanity, even as her family is worn down by the life. This is the basic goto distinction for "Who She Is".
No Stranger to Violence = She knows combat. She LIKES combat. All sides of her family have made sure that, regardless of anything else, she knows how to throw a punch and take one. This has had not-really-positive effects on her mental health, and when she is stressed out she tends to be somewhat menacy and glowery.
Smarter than She Looks (and Sometimes Acts) = She is young, fit, pretty, and a bit impulsive... and really does know better than to act the way that she does, both from the knowledge she has about the superhero community and her innate intelligence (which may have been helped by the generational aftereffects of the super-soldier serum taken by her great-grandmother). Additionally, she can be underestimated by older, more established heroes/villains as "just a kid".
